This spoof of miniseries that chronicle the dynastic, multigenerational sagas of dysfunctional families is a grand spectacle. Each episode is introduced by "Spoils" author Eric Jonrush (Will Ferrell) and the adventure commences with entrepreneur Jonas Morehouse (Tim Robbins) hoping to strike it rich in the oil fields of Texas, while his adopted son, Devon (Tobey Maguire), begins an affair with his daughter, Cynthia (Kristen Wiig)
